Model: WS80

Introduction

Thanks for your purchasing this WS80 6-in-1 Ultrasonic Sensor Package. This device measures wind speed, wind direction, temperature, humidity, UV Index and solar  radiation. The Ultrasonic Sensor Package is solar powered and sends data to the receiver via a low-power radio. The data can be streamed by GW1100 Wi-Fi Gateway (sold  separately) or HP2551/HP2553 console display (sold separately); and can be viewed on our WS View Plus or Ecowitt App application after the Wi-Fi configuration done. To  ensure the best product performance, please read this manual and retain it for future reference.

Table: Package content
If any component is missing from the package, or broken, please contact our Customer Service department to resolve the issue.
Note: Batteries for the ultrasonic anemometer are not included. You will need 2 AA size Lithium battery for the ultrasonic anemometer, which is primarily for startup and backup purpose. After setup and during normal operation, the unit is getting its power from solar cell.
Note: There’s a built-in heat plate in the 6-in-1 sensor package body, if the lowest temperature at your place is below -3°C, or 26.6°F, and the weather is mostly snowy or rainy, then you may need to activate the heater by supplying an external 12V/1A power to the sensor heating element for melting accumulated snow or ice, which can influence wind measurement accuracy significantly. Please contact us at support@ecowitt.com for the extension cord information if needed.
There’s a built-in thermostat inside the anemometer sensor to control the power supply for the heat plate, which will automatically turn on below 0℃ (30℉ ) and  automatically turn off above 10℃ (50℉ ).

Setup Guide

4.1 Install batteries in sensor package
Open the battery compartment with a screwdriver and insert 2 AA batteries in the battery compartment, and press “Reset” button, the LED indicator on the back of the  sensor package (item 4) will turn on for 3 seconds and then flash once every 4.8 seconds indicating sensor data transmission. If you did not pay attention, you may have  missed the initial indication. You can always press the reset button to start over. Make sure you see the flash once every 4.8 seconds.
If sensor has been put outside for some time, and solar panel has charged up the internal accumulator fully or partially, if you install the 2 AA backup battery, the system  might not start up properly. So you can always make a system reset by press the “Reset” button.

Figure 2: Battery installation diagram

Note: Please make sure the battery is inserted correctly for its polarity as the system needs its initial power from this backup battery to start up the system before solar panel charges up the accumulator and supply system power afterwards. when in high altitude area, during wintertime, sunshine time is short, thus system needs to be powered from this backup battery, we recommend Lithium batteries to be used for cold weather climates. Please avoid alkaline batteries, especially when internal heater is to be activated during cold and wet weather conditions as when heater activated, the trapped heat inside will warm up internally, and alkaline batteries are extremely susceptible to leakage when temperature is over certain limits.

4.2 Mount ultrasonic anemometer assembly
4.2.1 Before you mount
Before installing your outdoor sensor in the permanent location, we recommend operating the device for one week in a temporary location with easy access. This will allow  you to check out all of the functions, ensure proper operation and familiarize you with the device performance.

4.2.2 Mounting

•  You can attach a pole(not included) to a permanent structure and then attach the sensor package to it (see Figure 3-8).
• The U-Bolts will accommodate a pole diameter of 1.25-2 inches (pole not included).

1. Install the base on a pole (1.25inch~2inch) as Figure 3. Figure 3: Sensor package mounting diagram 6-1

2. Pass the connector cord through the arm tube as Figure 4: Figure 4: Sensor package mounting diagram 6-2

3. Attaching the arm tube to the Ultrasonic Sensor as Figure 5.
   Figure 5: Sensor package mounting diagram 6-3

4. Install the base with U-bolts and threaded nuts to a pole (not included) as Figure 6 shows:Install each M6 nut in the order 1,2,3 then 4. Do not tighten with an impact driver._ Hand tighten, then a half turn/180° No more. If your mounting pole is a soft material (wood, pvc, etc. you may need to retighten the M6 nuts when you perform your maintenance every 3 months.
   Figure 6: Sensor package mounting diagram 6-4

5. Insert the arm tube into the base as Figure 7. Be sure to line up the small hole in the arm with the holes in the base. Insert the machine screw through the holes in the  base and arm. ( if you don’t need to power up the heater, you should keep the power cord terminal inside the mounting arm and this can make the installation looks neat  and tidy. You may take it out when needed.)
   Figure 7: Sensor package mounting diagram 6-5
   Make sure the mounting pole is vertical, or very close to it. Use a level as needed.

6. During wintertime, to prevent ice formed on the reflection surface, The package including a 3M extension cord ,Please connect the cord to the connector that client  want as Fingure 8 show
   Figure 8: Sensor package mounting diagram 6-6

7. If optional extension cord is added, connect extension cord and then connector AC adaptor as Figure 9 show:

Figure 9: Sensor package mounting diagram 6-7

Finally, place the sensor package on top of the prepared mounting pipe. The U-Bolts should be loose enough to allow this but loosen the nuts as necessary. Once placed,  hand tighten all four nuts, taking care to do so evenly. Do not use a wrench yet!Now you will need to align the whole package in the proper direction by rotating it on top of the mounting pipe as needed. Locate the arrow labeled “NORTH” that you will find on top of the connector tube of the sensor package (item 6). You must rotate the whole sensor package until this arrow points due north. To achieve proper alignment, it is helpful to use a compass (many cell phones have a compass application). Once rotated in the correct orientation, lightly tighten the bolts a little more (use a wrench) to prevent further rotation.
Note: In Southern hemisphere, it is not necessary to change the orientation to SOUTH as its solar panel is a rounded type and it is orientation free for its charging capability.
Make sure the mounting tube for the sensor package is installed vertically (use a level at 90-degree offsets around the tube). Adjust the mounting pipe as necessary. Next also  make sure the mounting of the anemometer body on the pipe is level. If it is not, wind direction and speed readings may not operate correctly or accurately. Adjust the  mounting assembly as necessary.
Make sure you check, and correct if necessary, the north orientation again, as the final installation step, and now tighten the bolts with a wrench. Do not over tighten, but make sure strong wind and/or rain cannot move the sensor package.

4.2.3 Reset Button and Transmitter LED
In the event the sensor package is not transmitting, reset the sensor.
Using a bent-open paperclip, press and hold the RESET BUTTON (item 12) to affect a reset: the LED turns on while the RESET button is depressed, and you can now let  go. The LED should then resume as normal, flashing approximately once every 4.8 seconds.
